Red wine and mustard do wonderful things for this tender cut of steak.

Recipe Ingredients

  • 2 tablespoons olive oil
  • 3 cloves garlic, minced
  • 1 teaspoon chopped fresh parsley
  • 1 teaspoon chopped fresh thyme
  • ⅓ cup dry red wine
  • ½ teaspoon dry mustard powder
  • salt and pepper to taste
  • 4 (8 ounce) flat iron steaks
  • 2 cloves garlic, minced
  • ½ teaspoon dry mustard powder
  • ½ teaspoon olive oil

Cooking Directions

  1. 1 Whisk together 2 tablespoons of olive oil, 3 cloves minced garlic, parsley, thyme, red wine, 1/2 teaspoon mustard powder, salt, and pepper until combined. Pour into a resealable plastic bag over the flat iron steaks. Squeeze out excess air, seal, and marinate for 1 hour at room temperature, or 4 hours in the refrigerator.
  2. 2 Preheat an outdoor grill for medium-high heat and lightly oil grate. Stir together 2 cloves minced garlic, 1/2 teaspoon mustard powder, and 1/2 teaspoon olive oil in a small bowl and set aside.
  3. 3 Remove steaks from the marinade, shake off excess, and discard remaining marinade. Cook on preheated grill to desired degree of doneness, about 4 minutes per side for medium-rare. Brush with reserved garlic mixture before serving.

  4. LIZCANCOOK--- I haven't yet tried this recipe...however it is on my to eat list this weekend.

The 4 minute per side was I'm sure - Read more ...

  6. Excellent flavor. Easy to make. I made this recipe just as it appears on all recipes with the exception that I mixed everything in the bag (no extra dirty bowl).
